THI: STORKS. 97 



Eggs. From four to seven in number ; uniform brownish- 

 ol.vc. Axis, i '85-2*0 inches; diam., 1*45 -1*5. 



THE STORKS. SUB-ORDER CICONII. 



The Storks are very closely allied to the Heron, and have a 

 bridged, or " desmognathous," palate. They differ, however, in 

 several important particulars from the foregoing birds, as they 

 have no powder-down patches, and no pectination, or " comb- :) 

 like process, on the middle toe. Both toes are webbed at the 

 base, the outer one especially, but the chief difference is found 

 in the position of the hind-toe, or hallux, which is elevated 

 above the plane of the other toes, and is not on the same level 

 with them.

As regards the British species, the characters given above 

 are sufficient to distinguish the Storks from the Herons and 

 Ibises.
